Bruce, I agree with the others on this thread.  While many of the folks I trade with are able to use pre market data, I am unable to be helpful in this arena.  I am interested in playing morning gappers and need to understand the volume associated with those gappers.  I really need to be able to scan for gap plays that have a defined volume range.  I see  posts on this subject going back a bit.  Is any progress being made?
